Screenwriter Black, 43, also shared the news, by posting another shot of them looking loved up.

He wrote alongside it: “A very happy #ValentinesDay from ours to yours. 👨‍👨‍👦.”

Daley met Black in the 2013 and came out as gay in December of the same year.

The sports star said at the time: “I’d never felt the feeling of love, it happened so quickly, I was completely overwhelmed by it to the point I can’t get him out of my head all the time.”

He proposed to the Milk writer in 2015 and they tied the knot two years later, with romantic Daleysinging: “Romeo, Romeo, wherefore art though, Romeo?” to his fiance before the ceremony at the fairytale Bovey castle.

Just 50 close friends and relatives gathered at the lavish five-star golf resort in Dartmoor national park, 48 kilometres from Plymouth, Devon, where Daley grew up.

The exciting baby news comes just weeks after Daley put his London flat up for sale.

Daley and Black had previously had a long distance relationship with him being in London and Black in LA.

He admitted previously that their marriage was “far from perfect” and the distance between them was just one of their struggles.

Daley shared: “Our relationship is far from perfect. We have really tough times and struggles. For example, we went long distance for a very, very, long time: he was in LA, I was living in London. We would spend sometimes five weeks apart.

“And it’s something that was really, really tough and we’ve had to make massive and dramatic changes in our lives in order to be able to live together and see each other all the time. So, it’s not all plain sailing.”
